BACKGROUND OF THE INVENTION This invention relates to the treatment offibrous glass and particularly to the treatment of fibrous glass fabricto improve its esthetic properties and appearance.

Fiber makers have sought to alter the shiny and slippery characteristicsof glass fiber fabrics, so that they appear more like cotton and woolfabrics. The dyeability of glass fabrics presents a different problemthan that presented when dyeing cotton and wool; this is especially truewith respect to such properties as colorfastness, washfastness, andcrocking. Many improvements have been made in these areas in the lastdecade.

However, when glass fabrics are treated according to the inventiveconcepts, hereinafter described in greater detail, the fabrics have anappearance that cannot be duplicated in conventional fabrics. Specificreference is made to the fabrics ability, through varying the amounts offilamentary and textured yarn*(*Filamentary yarns are defined herein asa generally parallel arrangement of smooth, multifilament continuousstrands lying closely together, that are formed continuously, bymechanical attenuation and gathered upon a collet. Textured yarns havetheir genesis in filamentary yarns, but are post treated to impartbulkiness thereto. Reference is made to a text entitled Woven Stretchand Textured Fabrics" by Berkeley L. Hathome (1964), p. 9-10, whichfurther defines textured yarns.) and by varying the weave patternstherein, to adsorb varying amounts of pigmented dispersions on thedifferent yarns that make up the fabric and still possess good contrastbetween the pigmented dispersions.

The effect given to fabrics composed of filamentary and textured glassyarns when treated in accordance with the present invention, is that itappears that the fabrics were woven from yarns of different color andtone, when in fact, the fabrics were woven from undyed yarns. The degreeof bulkiness possessed by glass yarns when incorporated into a fabricallows many variations in the degree of color pickup when the fabric istreated with a multiple dye system. Textured yarns, it is believed,possess a higher potential than filamentary yarns i.e. more exposedsurface area carrying a negative charge, thereby enabling a fabriccomprising both yarns to be selectively colored.

Glass fabrics when treated by the inventive concept show unique utilityin the drapery, bedspread, and wearing apparel fields and possess goodwashfastness, lightfastness and crockfastness.

It is, therefore, an object of the present invention to provide methodsfor imparting decorative effects on the surfaces of glass fibersurfaces.

It is another object to produce glass fabrics, composed of filamentaryand texturedyams, wherein it appears that the fabrics are woven frommultiple colored yarns.

It is still another object to produce glass fabric composed offilamentary and textured yarns, wherein the degree of contrast in coloris sharp and uniform throughout the fabric.

Other objects and advantages will be apparent from the followingdescription.

Our glass fiber fabrics possess an advantage over glass fabrics finishedby conventional methods and over fabrics composed of cotton, wool,organics, etc. because conventional apparatus is employed such asdescribed in US. Pat. No. 3,065,103 for heat cleaning the glass fabricand for applying resin bonded pigmented finishing systems theretocomprising various colorants, including aqueous dyestuffs and pigmentdispersions. Emphasis is made on the fact that in line equipment is usedto get the desired effect on glass fabrics.

SUMMARY OF THE INVENTION When the inventive concept is employed on glassfabric composed of filamentary and textured yarn, each yarn therein iscapable of adsorbing a specific amount of finish, according to thesurface area of the yarn itself, the filamentary yarns of the fabric,after a first padding of finish containing a colorant, appear darker incolor than the textured yarns. This effect may be theoretically creditedto the fact that in filamentary yarns, the filaments are generally in atightly packed parallel relationship, so that the amount of dye on allthe filaments acts in synergism, whereas in textured yarns, composed ofrandomly oriented, loosely packed filaments, this effect does notappear. When the fabric is exposed to multiple finish compositions, eachhaving a different color or tone, the textured yarns have the capacityto adsorb more than one finish, depending upon the degree of bulkinessof said yarns, whereas the filamentary yarns are substantially satisfiedafteradsorbing a single finish composition.

It has been thought that by adding a cationic flocculating agent towater and applying the solution as a finish to glass fabric and dryingthe same, that a subsequently applied finish, containing a colorant, iscaused to precipitate out or flocculate pigmented particles. Thesepigmented particles apparently migrate and attach to the textured yarnsalmost to the exclusion of the non-textured yarns in the fabric. Thepigmented particles are permanently fixed on the textured yarns bydrying the fabric.

Another possible explanation of why the filamentary yarns exhibit adeeper color than the textured yarns might be due to a capillaryattraction of the dyestuff to the filaments making up the yarn. Thiscapillary attraction might be stronger than the pressure used toremove/excess finish from the fabric, but only in the filamentary yarns,and in effect may hold more of the finish than the textured yarns,thereby substantially satisfying the adsorptive capacities of thefilamentary yarns.

The effect of such adsorption capacities of the yarns and the effect ofusing a cationic flocculating agent in a separate finish, is that thefabric appears to have been woven from a number of differently coloredyarns. Upon close examination of the fabrics, it is observed that thedecorative effect imparted thereto is not similar to that of kissprinting or silk screening but, in fact, has a higher qualityappearance.

It has been observed that after a first padding of the fabric through afinish containing a first colorant, the filamentary yarns have retainedsubstantially more of the first colorant than the textured yams.Pressure exerted on the dyed fabric affects the textured yarns much morethan it does the filamentary yarns. The textured yarns are resilient andare thereby capable of having more finish expelled therefrom than thefilamentary yarns which are substantially rigid in comparison. Since thetextured yarn has resiliency imparted thereto because of its bulkynature, it springs back to its original shape so that those fibersmaking up the parameters of the diameter of the textured yarn appearwhite in color or substantially void of the first dyestuff. Thisphenomenon is analogous to the behavior of a colored sponge, which afterhaving squeezed liquid therefrom, the outer portion of the spongeappears lighter in color than the inner portion. However, thisphenomenon does not occur in the filamentary yarns where the fibers aretightly compacted, thereby imparting to these fibers a deep shade ortone of the first colorant. The textured yarns have a larger availablecoatable surface area or potential than the filamentary yarns, andtherefore have the capacity when passed through a subsequent finishcontaining a second colorant to adsorb the latter, whereas thefilamentary yarns having been substantially satisfied by the firstcolorant, do not have this capacity to absorb the second colorant, andconsequently the fabric possesses differently colored yarns showing goodcontrasts to provide a novel and decorative effect. However, it is notenough that the fabric be composed of filamentary and textured yarns inorder that it appears as though it were woven from multiple coloredyarns. There must be applied to the fabric a material, such as acationic flocculating agent, which induces a subsequently appliedcolorant to selectively seek out the textured yarns of the fabric almostto the exclusion of the filamentary yarns. Furthermore, this materialmust be applied according to the inventive concept so that in lineproduction equipment may be employed.

It is preferable to treat the multiple finished glass fabric with awater soluble organo-metallic complex containing from six to 24 carbonatoms, such, for example, as stearato chromic chloride, laurato chromicchloride and complexes of aluminum, zirconium and titanium, and aqueoussystems of organo silicon compounds in the form of a silane, itshydrolysis product (silanols), or its polymerization product(polysiloxanes), wherein the siloxane has from one to three highlyhydrolyzable groups and an organic group attached to the silicon atomcontaining from one to 18 carbon atoms, as represented by the formula nSi x (4-1!) wherein X is a highly hydrolyzable group such as chlorine,bromine, iodine or other halogen; methoxy, ethoxy, propoxy or the likeshort-chained alkoxy group. n is a whole number of from 1-3 and R is ahydrogen group or hydrocarbon radical containing from one to 18 carbonatoms, such as methyl, ethyl, propyl, isopropyl, butyl, pentyl, vinyl,allyl, methallyl, chloromethyl, dichloromethyl, heptyl to octadecyl andthe like aliphatic group, an aryl or alkaryl group such as phenyl,tolyl, naphthyl, benzyl, monoand polyalkylphenyls, xylyl, mesityl,mono-, di-and tri-ethyl phenyls, methyl naphthyl, diethyl naphthyl,anthracyl, pheny] ethyl and the like, or an alicyclic group such ascyclopentyl, cyclohexyl and the like or a heterocyclic group in whichthe aforementioned organic groups may be substituted or unsubstituted,saturated or unsaturated. These materials normally impart hydrophobicityto glass fiber fabrics, thereby explaining why properties such ascolorfastness and lightfastness are greatly improved.

Treating the fabric having a first finish dried thereon with a cationicflocculating agent and drying the same, provides a high quality contrastin color between the filamentary yarns and the textured yarns.

Any cationic flocculating agent may be used to obtain selective coloringof glass fabrics containing textured yarns or roughened surfaces.Substantially all of the flocculating agent migrates to and is fixedonto the textured yarns of a glass fabric, when a treatment containingthe flocculating agent is applied to and dried upon the fabric, almostto the exclusion of the non-textured yarns in the fabric. A subsequentlyapplied finish solution comprising a colorant and a film former migratesto substantially only the textured yarns of the fabric. It is not knownfor sure whether there is a mechanical or a chemical bonding of thesubsequently applied finish to the textured yarns. This is especiallytrue when it is observed that anionic and nonionic colorants ordyestufis perform equally well.

Single or multiple cationic flocculating agents may be used in anaqueous finish solution for application to glass fabric previouslytreated with a finish comprising a colorant and a film former or to afabric that has been heat-cleaned. A flocculating retardant ordispersing agent may be optionally used in the finish solution that isapplied after the flocculating agent is applied and dried on the fabricto control the degree of flocculation or precipitation of the colorantonto the textured yarns. By applying the flocculating agent to the-glassfabric and then drying the same before application of a finish solutioncomprising a colorant and a film former, the various dye baths that areemployed in the inventive process are not contaminated or caused toprecipitate out, thereby ensuring a continuous uninterrupted process. Ifthe flocculating agent is not dried or if the flocculating agent isadded to the finish solution comprising a colorant and a film former, aflocculated mass results which builds up on the padder apparatus in avery short time and interrupts the process.

No specific flocculating agents have to be used, but it has beendetermined that an aqueous solution of a high molecular weight cationicsalt of a complex polyamine (Lufax 295 sold by Rohm & Haas Co.) and amodified polyarnide epichlorohydrin cationic resin (Reten 763 sold byHercules Inc.) is especially suitable because it provides an especiallygood hand in the treated fabric. Another cationic flocculating agentthat provides good hand is a dicyandiamide based cationic dye-fixative(Fixanol PNA sold by l.C.I. Inc.).

The percent by weight of cationic flocculating agent in an aqueoussolution varies as the desired effect varies. However, it has beendetermined that at least about 0.02 percent by weight of the cationicflocculating agent must be used to obtain some contrast in color.

Other cationic flocculating agents may be used, including for example,deacetylated chitin (polymeric acetamino carbohydrate),polyalkyl-polyamines, polyalkyl-polyamine fatty acid reaction products,amino aldehyde condensate dye-fixatives, methylchloride quaternary ofthe stearic acid amide of 1-(2-aminoethyl) 2-heptadecenyl-2-imidazoline,fluid oil in water type emulsions of low molecular eight polyethylenechemically stabilized with a cationic amine acetate derivative of a longchain fatty compound, dicyandiamide formaldehyde dye-fixatives, andcolloidal cationic thermosetting resinous reaction products of straightchain poly-functional amines and an aldehyde such as, for example, ureaformaldehyde resins modified with (a) polyamines includingethylenediamine, diethylenetriamine, tetraethylenepentamine, guanidine,phenylbiguanidine, or bisguanidine, (b) hydroxylamines such asmonoethanolarnine or diethanolamine, (c) cyanoamines such asdicyandiamide, polyphenylbiguanide or polyphenyl methyl biguanide, (d)aminoamides such as guanidine, or (e) quaternary ammonium salts such astetraethanol ammonium chloride, and methylated dimethyl anilinequaternary ammonium salts; and the reaction products of theseresin-modifying agents with formaldehyde, in the absence of urea, suchas tetraethylenepentamine-formaldehyde, bisbiguanidineformaldehyde,polyphenolbiguanide-formaldehyde and guanylurea-formaldehyde.

In order to control the degree of flocculation of subsequent finishescontaining colorants and the deposition rate of floccules onto thetextured yarns it has been found advantageous to employ a neutral sodiumsalt of a condensed aryl sulfonic acid '(Tamol SN sold by Rohm & HaasCo.) or the like with the subsequent finishes. These subsequent finishesare applied after the cationic flocculating agent has been applied anddried,

Our process comprises the utilization of conventional heat cleaningapparatus and padding apparatus as described in U.S. Pat. No. 3,065,103in order to impart colorfastness to glass fabrics. The improvements inthe present process lie in the treatment of the fabric after eachpadding-drying operation, with an aqueous solution of a cationicflocculating agent and drying the same before applying a subsequentcolor to the fabric. When a subsequent colorant is applied, the earlierapplied flocculating agent causes the colorant to be attracted to thetextured yarns and permanently fixed thereon by drying. Necessary,however, for the attainment of novel decorative effects on glass fiberfabrics is that the fabrics be composed of textured and filamentaryyarns or that the fabrics have raised or roughened surfaces thereon.

Generally, during the first padding operation, the fabric is exposed toa higher padder pressure than that used in subsequent paddingoperations. The reason for this feature is that is has been founddesirable to expel as much of the liquid finish as possible and stillsubstantially fulfill the adsorptive capacity of the filamentary yarnswithin the fabric, while leaving the textured yarns thereinsubstantially unsatisfied. Subsequently, the already treated fabric,after having been dried, is preferably directed through a paddingapparatus having a dip tank containing a solution comprising a cationicflocculating agent and is dried in a conventional multiple-pass oven.

Subsequent to the above treatments, the fabric is again exposed to adifferently colored finish solution and passed through the paddingapparatus in such a manner that as much finish as is possible isretained by the fabric, i.e., the padder pressure is minimal in order toinsure that the textured yarns in the fabric are substantiallysaturated. The differently colored finish migrates only to the texturedyarns apparently in the form of a colloid where it is fixed by drying,which causes bonding of the colorant to the textured yarns. Subsequentto drying, the fabric is optionally treated with a stearato chromicchloride complex and dried to insure colorfastness and washfastness ofthe fabric.

It has been found that by applying an aqueous solution of a cationicflocculating agent as a separate finish, and drying the same, betweenapplications of multiple finishes to the fabric, that in line apparatusmay be utilized without fear of contamination or clogging. However, ifthe flocculating agent is added directly to a finish comprising acolorant, flocculation or precipitation occurs which after a very shorttime clogs or builds up on the padding apparatus, thereby requiring adisruption in the process for repeated cleanings.

The cationic flocculating agent may also be applied to the fabric byspraying, roll-coating, knife coating, etc., on one or both sides of thefabric and dried. When the cationic flocculating agent is applied toonly one side of the fabric an additional effect is created, i.e., acolor reversible fabric results. Such a fabric contains only one coloron one side, and on the side containing the cationic flocculating agent,a multiple color effect is produced. When the fabric is coated ratherthan padded or immersed in a cationic flocculating agent the texturedyarns in the fabric are deeper in color. When the cationic flocculatingagent is applied to the fabric via spraying, it may be applied eitherbefore or after the application of a colorant thereto. However, when thecationic flocculating agent is applied prior to application of acolorant, it must first be dried in order to eliminate clogging of theapparatus. But, when the cationic flocculating agent is applied to thefabric after application of a colorant thereto, it is done prior to thedrying of the colorant so that the dye particles are afforded a chanceto migrate toward the textured yarns of the fabric.

Where the degree of texturization of the yarns making up the fabricvaries, so too does the number of paddings with differently coloredresin-pigmented systems. It has been feasible to obtain as many as threeto five colors in glass fabrics, with good color contrasts by varyingthe weave pattern, by using yarns having different degrees oftexturization, and by varying padder pressures during the paddingoperations. Depending upon the color and tone of pigmented dispersionsused in a multiple finishing system, usually the later applied pigmentscompletely mask the earlier applied pigments on the textured yarn, butthis is a function of the concentration of the pigments used, and alsotheir color tone. Any finishing system, such as those that use acrylthefilamentary yarns; this is not true of the textured yarns in the fabric.Consequently, when the fabric is subsequently passed through an aqueoussolution containing a cationic flocculating agent and dried andsubsequently passed through at least a second finish composition havinga different colorant, the textured yarns pick up such a largerpercentage of the second colorant than the filamentary yarns that ineffect the second colorant substantially masks out the first colorant onthe textured yarns resulting in a fabric composed of filamentary yarnscomprising substantially only the first colorant and textured yarnscomprising substantially only the second colorant. Usually, however,neither the first nor the second colorants exist in their true color inthe finished fabric because of slight contamination, but this is thoughtto be an advantage, as long as there is good contrast, because itsoftens the tones of the fabric.

DESCRIPTION OF PREFERRED EMBODMENTS The following example is provided asan illustration of the preferred embodiment of the inventive concept,but the invention is capable of other embodiments and of being practicedor carried out in various ways.

EXAMPLE I A glass fabric composed of filamentary and textured yarns washeat-cleaned to remove protective sizing, and subsequently paddedthrough a first aqueous finish solution (Finish A) comprising an acrylicfilm former, a silane, and a first colorant. The padder pressure wasestablished to remove as much finish from the fabric as possible (about40-50 psi) and then the fabric was dried in a multiple-pass oven for 1minute at 350 F.

The moisture content of the fabric just after padding and before dryingranged from about 12-15 percent by weight (dependent upon the weave andthe amounts of filamentary and textured yarns in the fabric). Thispercentage was suficient to substantially saturate the filamentary yarnsof the fabric but left the textured yarns therein substantiallyunsaturated.

The fabric with the first finish dried thereon was then padded throughan aqueous solution (Finish B) comprising a cationic flocculating agentwherein the padder pressure was established to be from about 20-30psi.The fabric was subsequently dried at 350 F. for 1 minute. The cationicflocculating agent apparently allows the textured yarns to attract asubsequently applied colorant to the exclusion of the non-textured yarnswherein the colorant is fixed onto the textured yarns of the fabric bydrying. Without the use of a cationic flocculating agent betweenapplication of finishes comprising colorants, there is no sharp contrastof colors in the fabric.

Thereafter the fabric, having a dried deposit of the first finish and acationic flocculating agent dried thereon, was padded with a secondaqueous finish solution (Finish C) comprising an acrylic film former, asilane and a second colorant, different in color from the firstcolorant. An important feature herein was the establishment of a padderpressure that allowed as much of the second finish as possible to beadsorbed by the fabric, particularly the textured yarns therein. Thispadder pressure ranged from about -15 psi. Subsequent to the padding,the fabric was dried for 1 minute at 350 F. in a conventional multiplepass oven.

A high degree of contrast between the colorant of the first finish andthe colorant of the second finish was observed on the fabric and itpossessed good hand. The filamentary yarns of the fabric comprisedsubstantially all of the first colorant, and the textured yarns,depending upon the degree of texturization, comprised substantially allof the second colorant. When the degree of texturization of some yarnswas not as great as in other yarns, an ancillary benefit resultedbecause of contamination of the first and second dyestufis thereon orfailure of the second dyestuff to mask over the first colorant whichtended to add a third color tone to the fabric.

The fabric, as treated above, was subsequently padded through a stearatochromic chloride complex solution (Finish D) at a padder pressure offrom about 20-30 psi and dried at 350 F. for 1 minute in a conventionalmultiple pass oven. This stearato chromic chloride padding appeared toinsure good colorfastness and washfastness to the treated fabric.

The multiple-color effect was similarly effected when a glass fabric wasprovided with embossrnents or raised surfaces on various areas thereofso that in effect the embossed areas functioned as the textured yarnsabove.

Similarly, a pattern was effected on a glass fabric, whether composed ofall filamentary yarns or a combination of filamentary yarns and texturedyarns, when a discontinuous fihn or coating of the cationic flocculatingagent was applied to the fabric, such as for example, by a roller havinga disruptive surface or by printmg.

Compositions of the finishes used above were as follows:

Finish A Ingredients Weight Non-ionic self-crosslinking acrylic 2.00emulsion having 46.0% solids Copolymer of methyl hydrogen silicone 2.00and dimethyl silicone Glycidoxy-propyltrimethoxysilane 0.25 Methanol L00Phthalocyanine Green, aqueous dispersion, 2.00 25.8% solids Water 92.75

54.2% solids Water 79.00

Total 100.00%

Finish D Ingredients Weight Stearato chromic chloride complex 2.00solution Water 98.00

Total l00.00%

An ignition loss test was conducted on the fabric treated as describedabove. The result was as follows: After the padding and drying of FinishA on the fabric the ignition loss was approximately 1.50 percent andafter the padding and drying of Finish D on the fabric the ignition losswas approximately 3.50 percent. The difference in ignition loss on thefabric from Finish A to Finish D is attributed to the largest extent bythe amount of Finish C attracted by and fixed onto the textured yarnsmaking up the fabric.

Obvious variations can be made without departing from the spirit andscope of the appended claims.
